CNContactStore Save Error

CNContactStore's executeSaveRequest(_:) method throws an error according to the documentation.

I am trying to catch this error in a do/catch, but I cannot figure out what error I need to catch.

do{
  try store.executeSaveRequest(saveRequest)
} catch *???* {
  //alert the user
}

What is supposed to replace the ???'s in the code above?

You have a few options actually.

Catch any error without knowing the error

catch {...}

  1. Catch any error with the specific error message

catch let error { // Use error }

  1. Use exhaustive catch clauses to handle specific errors using the CNErrorCode enum.

    enum CNErrorCode : Int {

    case CommunicationError
    case DataAccessError

    case AuthorizationDenied

    case RecordDoesNotExist
    case InsertedRecordAlreadyExists
    case ContainmentCycle
    case ContainmentScope
    case ParentRecordDoesNotExist

    case ValidationMultipleErrors
    case ValidationTypeMismatch
    case ValidationConfigurationError

    case PredicateInvalid

    case PolicyViolation
}
